Well, I recently finished 100% completing Fortune Summoners (finally) and it was one of the best games I've played in awhile simply due to the satisfying difficulty. Every time the game got easy I'd start the next dungeon and my frustrations would be thoroughly renewed. It was always rewarding once I got used to the new enemies and improved my tactics, though, so I loved it. The localization was excellent, as well, of course.
With that I await the next CF release so whenever you guys want my money...
